2 Claims.

The invention aims to provide a new and improved dyeing apparatuswhichmay be used to equal advantage for dyeing cotton or the like inpackages, or batches of raw stock, and may be quickly and easily changedin the most simple manner, to adapt it for either use.

A further object is to provide a simple and effective arrangement forfluid-tightly connecting a dye passage of a package carrier with a dyepassage in the vat bottom, and for permitting easy removal of saidcarrier for the purpose of unloading the same or'to permit thesubstitution of a perforated false bottom which is employed when theapparatus is to be used for raw stock dyeing.

Yet another object is to .provide a novel arrangement in which afollower which is provided to rest on any batch of raw stock being dyed,coacts with other parts in securing the package carrier in operativeposition when packages are to be dyed.

A still further aim is to provide a novel and advantageous bottomstructure for the vat having an effective joint member which cooperateswith another joint member on the package carrier to connect dye passagesof said bottom and carrier with each other.

With the foregoing and minor'objects in view, the invention resides inthe novel subject matter hereinafter described and claimed, descriptionbeing accomplished by reference to the accompanying drawings.

Figure 1 is a vertical sectional view showing the apparatus conditionedfor package dyeing.

35 Fig. 2 is a sectional view illustrating the mannef in which thepackage carrier and the packages are bodily insertible into or bodilyremovable from the vat when the cover of the latter is removed.

Figure 3 is a sectional view showing the apparatus conditioned for rawstock dyeing.

Figure 4 is a top plan view of the vat bottom.

In the drawings above briefly described, a preferred construction hasbeen illustrated, and while this construction will be ratherspecifically explained, it is to be understood that variations may bemade within the scope of the invention as claimed.

A vat 5 is provided, the bottom of which is denoted at 6, and aremovable cover at I, suitable clamps 8 being provided for holding saidcover in closed position. Below the cover I, a perforated follower plate9 is provided, said plate being adapted to rest upon a batch of rawstock when the latter is to be dyed, said follower plate being connectedby suitable connections III with the cover 1 in such manner that saidfollower plate may move vertically. The connections i0 may well be ofthe construction disclosed in my co-pending U. S. application Serial No.251,438, filed January 17, 1939, and they have been shown of thisconstruction.

The base or bottom 6 is provided with an upstanding continuous flange lldisposed against or near the side wall of the vat 5 for the purpose ofsupporting a perforated false bottom l2-when the apparatus is to be usedfor dyeing raw stock (Fig. 3). This false bottom then coacts with thefollower plate 9 in properly holding the batch of raw stock, and saidfollower plate may move upwardly and downwardly as required and willserve to prevent channeling in the usual manner. When the apparatus isto be used for dyeing packages of cotton or the like, such as thoseindicated at l3 in Figs. 1 and 2, the false bottom I2 is removed but thefollower plate 9 then performs another function as will be hereinafterdescribed.

A carrier I4 is provided for the packages l3, said carrier preferablyconsisting of a hollow disk having a perforated top plate 15, theperforations of which communicate with the interior [6 of said hollowdisk. The lower side of the disk is provided with a central dye passagei1 communicating with the interior I6 and adapted to communicate withthe upwardly open end 18 of a dye passage l9 in the bottom 6, a specialjoint 20 being provided to establish a fluidtight connection between thetwo dye passages. Thejoint 20 consists of complementary joint members onthe base 6 and the carrier M respectively, said joint members beingpreferably constructed in the manner described below. I

The central portion of the bottom 6 is provided with an integralupstanding boss 2|, and the passage end l8 opens centrally through theupper end of said boss. Around this passage end l8, the boss 2i isprovided with a continuous upwardly open groove 22 in which a suitablepacking ring 23 is suitably secured, said packing ring being upwardlyexposed for contact with the lower edge of a circular flange 24 which isformed integrally with and projects downwardly from the carrier l4,around the passage IT. The upper side of the packing ring 23 is in aplane below the upper end of the boss 2|, and this boss is peripherallybeveled at 25 above said ring to guide the flange 24 into proper seatingrelation with the ring 23 when the carrier I4 is inserted into the vat.

The carrier I4 is provided with a central upstanding post 26 which isrigidly secured at 20' thereto. When the apparatus is assembled fordyeing packages such as II, the post 28 contacts with the center of thefollower plate 9 and supports the latter as seen in Fig. l. The lowerend of a vertical screw 21 which extends through the cover 1 then abutsthe follower plate 8 for the purpose of downwardly forcing said followerplate to similarly move the post 28 and carrier i4, thereby holding theflange 24 tightly against the packing ring 23 to prevent leakage of dye.

The screw 21 is preferably threaded througha yoke 28 which is secured byscrews or the like 29 upon the cover 7, said screw being provided with alower unthreaded portion 30 which passes through a suitable stuiflng box3i carried by said cover. Preferably a swiveled foot 32 is provided onthe lower end of the screw, but this is not absolutely essential.

The passage is may constitute either the dye inlet or the dye outlet andthe same is true of a pipe 33 which is shown connected with the cover 1.It is preferable that the bottom 8 be provided with an integralhorizontally elongated portion 34 extending to its periphery in orderthat the passage i9 may be formed therein, overcoming the use of anumber of separate pipe connections and the like. The outer end of theportion 34 may well have a small foot 35 cooperating with longer feet 36projecting downwardly from other portions of the bottom 6, for thepurpose of supporting the latter upon a floor or the like.

With the various parts related as shown in Fig. 1, the complementarymembers of the joint 20 are held tightly engaged and dyeing of thepackages l3 may be efiectively carried out. The dyeing operation havingbeen completed, the cover 1 is removed, the carrier i is also removedfor unloading as shown in Fig. 2, and upon reloading may be reinsertedin the vat if other packages are to be dyed. Before removing the cover1, the screw 27 is of course released.

If raw stock is to be dyed, the carrier I4 is not used. Instead, theperforated plate i 2 is inserted and supported upon the flange H as seenin Fig. 3, the screw 2-! being then raised will- 'ing an upwardly opendye ciently to prevent it from interfering with the desired verticalmovements of the follower plate 9 during the raw stock dyeing operation.

It will be seen from the foregoing that novel and advantageous provisionhas been made for carrying out the objects of the invention, and whilepreferred details have been disclosed, attention is again invited to thepossibility of making variations within the scope of the invention asclaimed.

I claim:

1. A dyeing apparatus comprising a vat having an upwardly open dyepassage in its bottom, a removable cover for said vat, a follower belowsaid cover, means connecting said follower with said cover and mountingsaid follower for vertical movement with respect to said cover, acarrier for packages to be dyed, said carrier being removably receivedin said vat and having a downwardly open dye passage in communicationwith said upwardly open dye passage in the vat bottom, means projectingupwardly from said carrier and supporting said follower, and meanscarried by said cover forforcing said follower downwardly, therebyforcing said follower supporting means and said carrier downwardly tohollld said passages in communication with each ot er.

2. A dyeing apparatus comprising a vat havpassage in its bottom, aremovable cover for said vat, a follower below said cover, meansconnecting said follower with said cover and mounting said follower forvertical movement with respect to said cover, a carrier for packages tobe dyed, said carrier being removably received in said vat and having adownwardly open dye passage in communication with said upwardly open dyepassage in the vat bottom, a central post projecting upwardly from saidcarrier and supporting said follower, and a central thrust devicecarried by said cover for forcing said follower downwardly, therebyforcing said post and said carrier downwardly to hold said passages incommunication with each other.
